680 Sli Disappointing - Page 8

However, I expected to be able to run games like BF3 maxed at 1080p never dropping below 60fps. It stays at 60fps a lot more than before, but occasionally, in certain spots, will drop in the high 40s on large 64 player maps. Is this normal? Can any set up run bf3 maxed @1080p and never drop below 60fps? A lot of people say 680 sli is overkill for this game @ 1080p. This is why I am asking.

Btw, both are overclocked to: 1189/3402

You shouldn't be getting drops with 2 x cards @ 1080P. I run crossfire HD 7950's @ 1440P maxed out with no fps drops. Is your CPU holding back the GPU's?

I myself noticed a difference when I went from x16/x8 to x16/x16, although people will say otherwise. I had much tighter frame rates, they increased a tiny tad, but the biggest diff for me was better mins.

I looked at my nvidia control panel and noticed global aa/af were on (by default). I set those to use application preferences and my graphics score in 3dmark was about 700 higher. After finding that, I looked for any other problems in that area and saw that the multi display was set to 2 or more monitors. I only have one. I am at work atm, but what would be the ideal control panel settings?

He already said that he gets those dips in B2K-maps mainly which are poorly coded. Not sure about you, but ppl with X79-rigs report about those random dips as well.

I set mine from multi to single monitor and it did not seem to make any diff for me

Yeah, I also did not notice any difference.

Finally had a chance to play metro last light with fraps tonight. With the game maxed and ssaa x2 I got a constant 60fps (vsync) with no drops ever. With ssaa x3 I had a pretty consistent 56-50fps with a very rare drop to the mid 40s from time to time. ssaa x4 I barely tested, but I got around 40fps. Does this sound normal?

Hmmm, I have not played Last Light yet, still working on 2033, but I think that would sound about right, is LL supposed to be as taxing as the first?

When i had 480 SLi, i never went below 60 either, CPU plays a large part in some of the larger maps, especially B2K maps.

Single GTX 480 can handle 60 FPS minimum with downgraded visuals...
